Abstract
A torch for use in analytic instruments includes a tube subassembly with substantially cylindrical nested inner and outer tubes with coincident central axes, the inner tube having a terminus. The torch also includes a removable injector extending at least partially in the inner tube and having an alignment feature, an inlet, an outlet, and a central axis that is coincident with the central axes of the inner and outer tubes, a seal having a channel for accommodating a portion of the injector, and a base for supporting the tube subassembly, injector, and seal. The seal has a complementary feature to engage the alignment feature of the injector to prevent axial misalignment of the injector and maintain a fixed gap between the terminus of the inner tube and the outlet of the injector.
Claims (22)
1. A torch comprising: a tube subassembly including substantially cylindrical nested inner and outer tubes with coincident central axes, the inner tube having a terminus; a removable injector extending at least partially in the inner tube and having a bump, an inlet, an outlet, and a central axis that is coincident with the central axes of the inner and outer tubes; a seal having a channel for accommodating a portion of the injector; and a base for supporting the tube subassembly, injector, and seal, wherein the seal has an internal groove for capturing the bump of the injector to prevent axial misalignment of the injector and maintain a fixed gap between the terminus of the inner tube and the outlet of the injector.
2. The torch of claim 1, wherein the seal has a plurality of flexible fingers defining the internal groove.
3. The torch of claim 2, further comprising: a screw for restricting movement of the flexible fingers and thereby prevent motion of the injector bump and retain the injector within the base.
4. The torch of claim 3, wherein the fingers have inwardly-sloped end portions to facilitate passage of the screw thereover.
5. The torch of claim 3, further comprising: an insert disposed in the base and having threads for mating with threads of the screw and barbs for retention within the base.
6. The torch of claim 1, wherein the injector has a tapered shape in the direction of the outlet.
7. The torch of claim 1, wherein the material of the injector is quartz.
8. The torch of claim 1, wherein the outer tube incudes an orifice for transmission of an ignition spark through the outer tube.
9. The torch of claim 8, wherein the orifice is a pattern of multiple microscopic holes.
10. A torch comprising: a tube subassembly including a substantially cylindrical nested inner and outer tubes with coincident central axes, the inner tube having a terminus; a removable injector extending at least partially in the inner tube and having an inlet, an outlet, and a central axis that is coincident with the central axes of the inner and outer tubes; an adapter having a bump and a first channel for receiving the injector; a seal having a second channel for accommodating a portion of the injector; and a base for supporting the tube subassembly, adapter, and seal, wherein the seal has an internal groove for capturing the bump of the adapter to prevent axial misalignment of the injector and maintain a fixed gap between the terminus of the inner tube and the outlet of the injector.
11. The torch of claim 10, wherein the seal has a plurality of flexible fingers defining the internal groove.
12. The torch of claim 11, further comprising: a screw for restricting movement of the flexible fingers preventing motion of the injector bump and retaining the injector within the base.
13. The torch of claim 12, wherein the fingers have inwardly-sloped end portions to facilitate passage of the screw thereover.
14. The torch of claim 10, further comprising: an insert disposed in the base and having threads for mating with threads of the screw.
15. The torch of claim 10, wherein the injector has a substantially cylindrical shape.
16. The torch of claim 10, wherein the material of the injector is alumina.
17. The torch of claim 10, further comprising one or more O-rings around the adapter to provide radial compression.
18. The torch of claim 10, wherein the outer tube incudes an orifice for transmission of an ignition spark through the outer tube.
19. The torch of claim 18, wherein the orifice is a pattern of multiple microscopic holes.
20. A torch comprising: a tube subassembly including substantially cylindrical nested inner and outer tubes with coincident central axes, the inner tube having a terminus; a removable injector extending at least partially in the inner tube and having an alignment feature, an inlet, an outlet, and a central axis that is coincident with the central axes of the inner and outer tubes; a seal having a channel for accommodating a portion of the injector; and a base for supporting the tube subassembly, injector, and seal, wherein the seal has a complementary feature to engage the alignment feature of the injector to prevent axial misalignment of the injector and maintain a fixed gap between the terminus of the inner tube and the outlet of the injector.
21. The torch of claim 20, wherein the alignment feature is a recess and the complementary feature is a bump.
22. The torch of claim 10, wherein the adapter includes an end stop for fixing the axial position of the injector in the first channel.
